The roll-out of the previous update - GDR2 - isn't even complete (thank you, carriers), and Microsoft is already pushing out the next one, GDR3. This update for Windows Phone 8 is the last one before 8.1 comes out next year, and brings with it a number of small improvements, such a close button in the multitasking view, a driving mode, support for newer hardware and 1080p displays, a rotation lock, and more.

There's no telling as of yet when Windows Phone 8 users will be getting the update, but non-branded phones will most likely get it first. On top of that, if you're a Windows Phone developer, you can get the update straight away.

I have a T-Mobile Lumia 925. The only thing they shoved on it was Wifi-calling which is really seamless. An update just occurred on my phone this morning for some reason. Windows Phone 8 just keeps getting better and two friends of mine put down Blackberrys for a Lumia this week. When the 1520 is available I'm going to trade up on T-mobile.
